Our rustic mantel shelf offerings includes this Cedar Shelf made from a select grade of timber with tight knot markings and two corbel brackets. Standard shelf depth is 8 1/2″ deep and 5 1/2″ tall, but you can increase the depth. The corbel brackets (unattached) are 4″ wide, 7 1/2″ deep and 8 3/4″ tall. This mantel shelf can be purchased with either its smooth sanded surface or its rough-sawn surface exposed: your choice. Also, you may increase the shelf depth up to a maximum of 11 3/4." View the smooth and the rough sawn surfaces in the Alternate Images! NOTE: We do not apply and this rustic shelf does not need a finish or sealer coat.
